Pennsylvania, have invented certain new and useful lmprovemeiits in Automobile Bumpers, of which the following is a speci-- lication.

This invention relates to automobile bumpers and more particularly to that type of devices adapted to be mounted on the forward portion of the vehicle trame to pre vent damage to the machine upon impact with the bumpers or parts of other machilies.

y The primary object of thev invention is the construction of a novelanfl improved form of bumper wherein the spring supporting` the bumper bar and the mounting thereof is of novel design and construction alorib ing provision for engaging` the bumpers of other machines regardless of the height thereof and thus inventing impact of the body of the .mae ine and the subsequent possible damage thereto.

A still further object of the invention resides in Athe construction of an automobile spring bumper for mountingY to the forward frame of a machine so that it may extend at a more or less considerable distance in advance ofthe front body to prevent dnm age thereof due to impact or collisionwith other. machines, said mounting being pro vided ivith an anti-rattling ,device which 35 also,prevcnts vibration of the said bumper.

Aiiothei' and very import/faut object of the inventiont relates to a spi-ingr mounted automoble'bumper including a novel and improved clamping device whereby the 40 bumper bar"may be easily removed from the springs for repairs or replacement with-- o'ut detaching the springs or removingl the same from the body of the machine.

A continued object of the invention will t be found to reside iii a spring bumper cousisting of comparatively' few but simple Y parts, capable ofbeing easily assembled and manufactured at an extremely low cost, highly eilieient, diirablc and rigid in con-- "5a struction, of universal application and pai',- vticularly desifrne'd and adapted to be attached to various types of machines andA otherwise meeting the rigid requirements andiwithstanding the tests of rough use to which devices of this character av e designed to overcome.

rigore l is a plan view showing the bumper attached to the forward part of a machine, A

Inga 2 is a front view ot the bumper.

Fig: 3 is a view taken on the line 3-3 of F191,

Fig. 4 is a sectional view through the :intirattling' device,

lig. 5 is a View taken on the line 5-5 of Fig. 5.

Referring;r now to the drawing wherein like parts designato similar and correspondingl parts iii the lspecification, .l desiguales a front portion ot an automobile having the usual front ends 5, of the side barsI ot`the frame oi the machine to which thc bumper now to be .described is mounted.l

The bumper proper is adapted to bc mounted or rigidly secured in any well known iiiaiiucr to the viront portion (if-thc side bars 5 and i'oi this purpose l have shown u pair ot' substantially if-shaped hangers preferably constructed o' wide, flat metal so as to lic. lush with thc hcad side bars and bc sccurcd llicrcto by a pair of U-,sliapcd fastening clcmcuts 7,18*' as' an elliptical spring; dcsignatcdiii its entirety by li. The loose or frec cud l5 of said spring.; normally ovcilics the, opposite cnil lo. which as abovc dcscribcd isiivcted to thc if-shaped hanger. and in order tosef cui-e the frcc cud l5 to thc said hanger, have provided :if U-shaped clevis member' i7 which passcs through the apertures iii tho i'espc-,ctive'eziis lll, il,` each legir portion of said clevis beingl provided with a resilient spring' l'l which bears against athreadcd. -iiut 19 and is prevented' from being removed 'rom said cievis by locking nuts 20 on -the end thereof.

From this construct-ion, it will be readily v secu that tlieclevis not only i'oiins a ready attachiiuhr device lor securing the cud of the frame to the. hanger, but, also all'oi'ds means for positioning the resilient springs 18 thereon to prevent rattling and vibration ofthe said spring and bumper bar when carried by the vehicle. It will of course be readily 14. I have shown a bumper bar 21 of channel iron. it benut;r readily apparent thatV either resilient` or rigid bumper bars 'are equally adapted to be secured to the. spring construction above desrribed. For the pur poses of securing` the bumper bar to the spring. I have shown'a substantialiy square attaching plate 22 with apertured ears 23 at its respective corners whereby Ushaped bolts 24 may embrace the bumper bar and be secured to the attachingplate Q2 by threaded `elements 24. By this construction the device lends itseltl to the easy and ready remval .of the bumper bar whenever desired to re pair or replace the same'withont in any way rearranging or removing either the spring or the hanger vfrom the machine? Since the hangers (5 arerigidly mounted it'will be furthermore seen that the impact to the bumper bar 21 will at ali times be taken up by the spring 14. Of course the attaching plate 22 permits the same and the bumper bar to be raised or lowered with respect to the said sprintr 14 to meet the desied needs,.it being;r readily understood that the frames of some automobiles are higher orlower than others and the ar 'rangement is in practice such as to afford the greatest amount of protection where the bumper is desired to be. used.

ln the accompanying..T drawings. I have illustrated my invention embodied in one form by way of example. and which in practice has been yfound to be highly satisfactory in obtaining the' desired results. It will be obvious however that other embodiments may be adopted and that various changes in` the details of construction may-be resorted to by those skilled in the art without departing from the spirit and scope of the-invention. It is furthermoreunderstood that the invention is not necessarily limited or ren stricted to the precise elements shown except;`

in so far as such limitations are specified in the subject matter hemar claimed.

Having shown and described my invention what I now claim as'new and desire to secure by Letters Patent of the U. H. is

1. in an automobile bumper construction comprisingl substantially V-shaped hangers for mountingonthe frame of an automobile, vertically arranged, elliptical springs supported by said hangersfand a transversely extending bumper bar detacha'biy and ad justably supported by. said springs.

2. ln an automobile` bumper construction comprising! substantially V-shaped hangers, for mountingr to the frame of an automobile, vertically arranged, elongated ellipicai springs rigidly supported by the tree c'ids of said hangers, a. transverse' bumper i-ar carried by said springs, attaching plates an i removable bolts embracing the hamper bar for detachabiy and adjustably securing saidl bumper bar to various positions with respect to the .springs and the hangers.4

3. in an automobilev bumper construction comprising snbstantiaily lif-shaped hangers for mounting to the, frame of an automobile, verticaily arranged, elongated elliptical springs rigidly supported by said hangers.` apertured ears formed in the tree ends of said hangers, clevis members passing' through said ears :For securing the free ends of said springs to the hangers, anti-rattling meansl carried by aid clevises, and a transverse bumper bar detachably secured and vertically adjustable with respect to said springsand hangers.

4. In an automobile bumper construction comprising,r substantially V-shaped hangers for mounting to the frame ot an automobile, vertically arranged5 elongated elliptical springs rigidy supported by said lumgers7 apertured-ears formed in the 'free ends ot said hangers and near the extremities there of, clevis members passingI through said cars' for securing'the free end of said springs to said hangers. anti-rattling` means carried by said clevises to prevent vibration oi said springs. a transverse bumper bar carried by the foi-.ward portion ot' said springs. attaching plates normally lying flush with the in terior of said springs, removable. Usbaped bolts embracing the said. bumper har and se.- cured to the att-aching plates whereby the said har may be vraised or iowered with respect to the springscr entirely removed from the springs.

ntcstimonywhereof, aiiix my signature hereto.
